Sustainable Agriculture

What is sustainable agriculture? The word sustainable has become very popular in recent years and it is now used to describe a lot of things. But what is sustainable agriculture? Simply put, sustainable agriculture is the production of plant and animal products, including food, in a way which uses farming techniques that protect the environment, public health,communities, and the welfare of animals. Sustainable agriculture allows us to produce and enjoy healthy foods without compromising the ability of future generations to do the same. The key to sustainable agriculture is finding the right balance between the need for food production and the preservation of environmental ecosystems. Sustainable agriculture also promotes economic stability for farms and helps farmers to better their quality of life. Agriculture continues to be the biggest employer in the world with 40% of the world’s population working in it. More from Sustainability: What is Sustainable Energy?What is Environmental Sustainability and Sustainable Development? What is Sustainable Development and what are its Goals?What is sustainable Living and 15 easy Ways for Sustainable Living?What is Sustainable Farming and Best Sustainable Farming Practices?Is Renewable Energy Sustainable?According to Wikipedia,“Sustainable agriculture is the act of farming using principles of ecology, the study of relationships between organisms and their environment. It has been defined as “an integrated system of plant and animal production practices having a site-specific application that will last over the long term.” Sustainability is a seemingly laudable goal – it tells us we need to live within our means, whether economic, ecological, or political – but it’s insufficient for uncertain times. How can we live within our means when those very means can change, swiftly and unexpectedly,beneath us? ~ Jamais Cascio If given the choice I’m sure we would all choose to consume natural chemical free food instead of food that is sprayed with pesticides and chemical fertilizers. Sustainable agriculture differs greatly from industrial agriculture where large volumes of crops as well as livestock are produced for sale using industrial techniques. Industrial agriculture relies heavily on pesticides and chemical fertilizers and other chemical enhancers. In the past decade the majority of food we ate has been grown in this manner. In 1996 only 20% of the corn in the United States was genetically modified, that number had reached 88% by 2006. However in the last couple of years, due to the negative aspects of the technique, there has been a slight shift towards the use of sustainable agricultural methods. Methods of Sustainable Agriculture 1. Crop Rotation: Crop rotation is one of the most powerful techniques of sustainable agriculture. Its purpose is to avoid the consequences that come with planting the same crops in the same soil for years in a row. It helps tackle pest problems, as many pests prefer specific crops. If the pests have a steady food supply they can greatly increase their population size. Rotation breaks the reproduction cycles of pests. During rotation, farmers can plant certain crops, which replenish plant nutrients. These crops reduce the need for chemical fertilizers. 2. Cover Crops: Many farmers choose to have crops planted in a field at all times and never leave it barren, this can cause unintended consequences. By planting cover crops, such as clover or oats, the farmer can achieve his goals of preventing soil erosion, suppressing the growth of weeds, and enhancing the quality of the soil. The use of cover crops also reduces the need for chemicals such as fertilizers. 3. Soil Enrichment: Soil is a central component of agricultural ecosystems. Healthy soil is full of life, which can often be killed by the overuse of pesticides. Good. soils can increase yields as well as creating more robust crops. It is possible to maintain and enhance the quality of soil in many ways. Some examples include leaving crop residue in the field after a harvest, and the use of composted plant material or animal manure. 4. Natural Pest Predators: In order to maintain effective control over pests, it is important to view the farm as an ecosystem as opposed to a factory. For example, many birds and other animals are in fact natural predators of agricultural pests. Managing your farm so that it can harbor populations of these pest predators is an effective as well as a sophisticated technique. The use of chemical pesticides can result in the indiscriminate killing of pest predators. 5. Bio intensive Integrated Pest management: Integrated pest management (IPM). This is an approach, which really relies on biological as opposed to chemical methods. IMP also emphasizes the importance of crop rotation to combat pest management. Once a pest problem is identified, IPM will mean that chemical solutions will only be used as a last resort. Instead the appropriate responses would be the use of sterile males, and biocontrol agents such as ladybirds. Benefits of Sustainable Agriculture 1. Contributes to Environmental Conservation: The environment plays a huge role in fulfilling our basic needs to sustain life. In turn, it is our duty to look after the environment so that future generations are not deprived of their needs. Sustainable agriculture helps to replenish the land as well as other natural resources such as water and air. This replenishment ensures that these natural resources will be able for future generations to sustain life. 2. Public Health Safety: Sustainable agriculture avoids hazardous pesticides and fertilizers. As a result, farmers are able to produce fruits, vegetables and other crops that are safer for consumers, workers, and surrounding communities. Through careful and proper management of livestock waste,sustainable farmers are able to protect humans from exposure to pathogens,toxins, and other hazardous pollutants. 2. Prevents Pollution: Sustainable agriculture means that any waste a farm produces remains inside the farms ecosystem. In this way the waste cannot cause pollution. 3. Reduction in Cost: The use of sustainable agriculture reduces the need for fossil fuels, resulting in significant cost savings in terms of purchasing as well as transporting them. This in turn lessens the overall costs involved in farming. 4. Biodiversity: Sustainable farms produces a wide variety of plants and animals resulting in biodiversity.During crop rotation, plants are seasonally rotated and this results in soil enrichment, prevention of diseases,and pest outbreaks. 5. Beneficial to Animals: Sustainable agriculture results in animals being better cared for, as well as treated humanely and with respect. The natural behaviors of all living animals,including grazing or pecking, are catered for. As a result they develop in a natural way. Sustainable farmers and ranchers implement livestock husbandry practices that protect animals’ health. 6.Economically Beneficial For Farmers: In exchange for engaging with sustainable farming methods, farmers receive a fair wage for their produce. This greatly reduces their reliance on government subsidies and strengthens rural communities. Organic farms typically require 2 ½ times less labour than factory farms yet yield 10 times the profit. 7. Social Equality: Practicing sustainable agriculture techniques also benefits workers as they are offered a more competitive salary as well as benefits. They also work in humane and fair working conditions, which include a safe work environment, food, and adequate living conditions. 8. Beneficial For Environment: Sustainable agriculture reduces the need for use of non-renewable energy resources and as a result benefits the environment. Due to population increase, it is estimated that by 2050 we will need approximately 70% more food than is currently being produced in order to provide the estimated 9.6 billion world population with their recommended daily calorie intake. This is by no means a small challenge, but unlike many other sustainability challenges, everyone can play a part. We all need to eat, but by simply reducing food loss and waste, as well as eating diets that are lower impact, and investing in sustainable produce, we can make a difference. From countries, to companies,right down to consumers,we all have a role to play. The challenge is simply making people care in a world where we are surrounded by such abundance.

FISH FARMING

                                           Fish farming
Fish farming or fishery is the culturing, raising or rearing of fish in a controlled environment for food or other useful purposes.
Controlled environment could be a man-made water body such as a pond, or an enclosed section of a natural water body.
Aquaculture is one of the branches of agriculture. The growing of plants and animals on land for food and other products is agriculture, while raising animals and plants in water is aquaculture.
Fish can be classified based on their habitat and morphology.
1.     Classification based on their habitat and morphology: There are two types of water habitats where fish are found. These are fresh water and salt water.
a.     Fresh water habitat: this refers to water which has no salt. Such water is found in rivers, ponds and lakes. Fishes found in such habitats include tilapia, electric fish, mudfish, carp, trout and moon fish.
b.     Salt Water Habitat: This refers to water body with salt taste. Such water is found in the sea and ocean. The fishes in this type of habitat include the shark, mackerel, sardine, cod (stock fish), skipjack and cottle fish.
2. Classification based on morphology: morphology refers to the form or structure of the fish. We have bony fishes and cartilaginous fishes.
a. Bony fishes: They are those that possess hard bone. Examples are tilapia, mud fish, catfish salmon and cart
b. Cartilaginous fish: they are those that possess soft bones. Examples are ray, shark and dogfish.
As Nigeria grows massively in population and government placing restrictions on importation of more and more agricultural products, paying attention to the agriculture business is our next gold. Fish farming is one of the various business opportunities any business minded Nigerians can look into.
Everywhere in the world, worldwide, the most common fish species used in fish farming are carp, salmon, tilapia and cat fish. While the last two, tilapia and cat fish are the most common species raise in Nigeria. Tilapia taste great and is one of the easiest fish to raise. It tolerates a wide variety of water conditions, including low oxygen levels and is resistant to diseases and parasite. Tilapia grows quickly under proper conditions.
Cat fish has an exceptional taste and it is resistant to disease and parasite.
Catfish grows quickly; a large fingerling can reach on pound within 5months

How to start home based fish farming business
First thing you will need to start a home based fish farming business is some basic knowledge about raising fish. To raise fish you will need some space in your backyard for digging a fish pond or space in your basement or anywhere else, if you want to raise fish in containers. Fish can be raised in any kind of fish tanks, containers, and tub.
One will need some basic knowledge about fish, so one needs to get as much knowledge as one possibly can about fish farming. The more knowledge you have the better chances you will have to succeed in your home based fish farming business.
Choose water from a reliable source, it could be well, borehole, or your municipal supply water will be fine. Once you have your pond or container, get your juvenile fish from a hatchery near you. Make sure you feed your fish with appropriate proper diet and take care of your pond and fish tank.
                

    There are three means of food for your fish:
1. Natural food: this is found naturally in the pond. This include; plankton, worms, and insect.
2. Supplementary feed: this includes kitchen waste or agricultural by-product.
          3.Complete feed: this is a carefully made fish feed, it is made by the experts who understand the perfect formula for the fish at a different stage.

In conclusion, one needs some basic knowledge about fish, so one needs to get as much knowledge as one possibly can about fish farming. The more knowledge you have the better chances you will have to succeed in your home based fish farming business.
